Peter Dunn and Margaret Marshman present the second of their data files articles in which they discuss the statistical investigation cycle which describes the whole process of conducting a statistical research study. [For "The Data Files: A Series of Articles to Support Mathematics Teachers to Teach Statistics," see EJ1259108.]

The College and Career Readiness Expansion project was a five-year, federally funded effort to implement early college strategies in comprehensive high schools. This report presents the results from a quasi-experimental impact study of the project and a mixed methods examination of its implementation. Results showed that the program increased the…

The purpose of the study was to update previous meta-analytic findings on the effectiveness of using similarities and differences as an instructional strategy. The strategy includes facilitating student comparison, classification, use of analogies, and use of metaphors. Previously, Marzano, Pickering, and Pollock reported a mean effect size of…

Most students think animals are more interesting than plants as a study topic believing that plants are inferior to animals because they are passive and unable to respond to external challenges, particularly biological invaders such as microorganisms and insect herbivores. The purpose of this study was to develop an inquiry-based learning unit,…

This article reports the development, validation and use of an instrument designed to provide teachers with feedback information, based on students' perceptions, about their classroom environments. The instrument was developed to provide teachers with feedback that they could use to reflect on their teaching practices and, in turn, guide the…

Educational researchers and teachers are well aware that misconceptions--erroneous ideas that differ from the scientifically accepted ones--are very common amongst students. Daily experiences, creative and perceptive thinking and science textbooks give rise to students' misconceptions which lead them to draw erroneous conclusions that become…

This study is a secondary analysis of data from the 1995 administration of the Third International Mathematics and Science Study (TIMSS). The purpose is to compare the breadth, depth, and recurrence of the typical physics curriculum in the United States with the typical curricula in different countries and to determine whether there are…

The National Assessment of Educational Progress (NAEP) is mandated by the United States Congress to survey the educational accomplishments of U.S. students and monitor changes in those accomplishments. For more than 25 years, NAEP has assessed the educational achievement of 4th-, 8th-, and 12th-grade students in selected subject areas, making it…

A major purpose of this study was to measure and compare the effectiveness of office procedures, model office, and cooperative office education courses in developing 12th grade students' office decision-making abilities as well as to compare their decision-making abilities with those of office supervisors and office workers. Two other purposes of…

Though a previous study examined the data for vocational-technical students provided by the National Longitudinal Study of the High School Class of 1972, it did not exhaust the possibilities for evaluation of the data. The current study concentrated on three specific areas of analysis: (1) educational characteristics of students and selected…

This is a record of the proceedings of the 30th annual conference of the Mathematics Education Research Group of Australasia (MERGA). The theme of the conference is "Mathematics: Essential research, essential practice." The theme draws attention to the importance of developing and maintaining links between research and practice and…
